That's a really weird thing to say, by what measures do you mean? In terms of market share, they are AWS, then Azure, then a big gap, then Google. In terms of maturity of the managed services, it's Azure, then AWS, then Google. Google in particular has a lot of "tickbox" features just to say they have them but when you drill down they are far more basic than either Azure or AWS.
Visual Studio is littered with SQL server and Azure tools which doesn't even make sense
Why doesn't it make sense? I use those tools regularly! The VS team, using their own product to develop their product, is generally super responsive to the user community.
The web portal is the best example, you can't use that with just one browser. Some things only works in Chrome, others are only broken in Chrome.
